听力原文： Motivation can come from three sources, two of them external and one internal. However, motivational sources differ in degree of effectiveness. Indeed, two of them can occasionally lead to negative outcomes.
The first end least effective form. of motivation is typically characterized by some kind of threat. There is often a fear of some unpleasant consequence. For example, "If you don't study hard, you'll fail your exam" or "If you don't finish your work on time, I'll have to fire you." People usually respond to threats of this kind, but they are likely to carry out their tasks with little enthusiasm and with minimum effort.
The second form. of motivation comes from a pressure or desire to please. You may be afraid of disappointing people you want to make happy. Students often study very hard in order to please their teachers and to achieve what their parents went for them. This kind of motivation also often works, but can sometimes be dangerous if what teachers and parents went is not the same as the student's own desire end ambitious.
Finally, there is the internal source of motivation, where the task is carried out because the individual is personally committed to it. With this kind of motivation, studying or working becomes a pleasure and not a duty. A wise man once said, "If a man finds a job he really loves, he will never work again in his life."
In life we are driven by a combination of all three forms of motivation. They coexist in educational systems, affecting students, parents end teachers. However, in our pursuit of better more effective education, we should constantly be aware of the three forms. We should seek above all to make the greatest possible use of the third kind — the personal motivation of the individual.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
In 1997, devotees of home electronics eagerly awaited the DVD player, a new device that could play movies without videotape, and with greater clarity. It caught on even faster than CD music players and within four years, DVD movies surpassed VHS tapes in sales. The DVDs success is just one example of a historic shift from analog to digital technologies. They began with computing and are now spreading to industries from banking to publishing. Products and services are shedding the limits of their physical form. to become encoded information that never degrades, can be reproduced perfectly and distributed around the world in minutes, or less.
Another example is photography: by the end of this year, the number of images captured digitally each day is expected to surpass the number of images captured on film. With digital cameras and other devices linked to personal computers, we can collect vast amounts of data, which fortunately takes up little or no closet space. Today's average personal computer has a hard drive that can store 300 times more information than a decade ago. Technologies, such as broadband e-commerce, are expected to be the primary means of delivering entertainment and media by the end of this decade. Even life itself is increasingly digitized. The human genome, the recipe for our genetic makeup, has been mapped and encoded and researchers are harnessing the power of computing to accelerate the development of new, lifesaving drugs.
The implications of this broad, digital revolution are enormous, although they tend to be over-shadowed by the struggles of high-tech industries to recover from the go-go years of the 1990s. Those struggles are real, yet there are reasons for optimism about a return to robust economic growth and job creation in the next several years. The digital innovations(创新)of the past two decades continue to bear fruit, so stay tuned for good news--digitally, of course.
Digital technologies really began to take form. when _______.
